The forehead represents Cheonjeong (Heaven Palace) or Gwanrokgung (Career Palace), mapping out early-life growth, scholarly capabilities, and professional promotions. A broad, high, and smooth forehead (like a suspended liver shape) denotes quick intelligence and early career success. Straight hairlines suit systemic bureaucracy, whereas M-shaped hairlines excel in creative leadership. Forehead lines, categorized as Cheonmun (senior help), Inmun (personal effort), and Jimun (junior support), signal life flows. Keeping the forehead clear and exposed maximizes professional opportunity.
